Description

  The present invention relates to an image forming apparatus, an image forming apparatus control method, an information processing apparatus, and a program.

  Conventional authentication methods include ID input, fingerprint authentication, vein authentication, and IC card authentication. These authentications require user operations and actions during authentication, and can be performed at a timing intended by the user. On the other hand, face authentication has been devised in which an imaging unit is provided in the image forming apparatus, and authentication of a person approaching the image forming apparatus is performed based on an image captured by the imaging unit. According to face authentication, authentication can be performed even if the user is away from the image forming apparatus within the imaging range, and no user operation or operation is required during authentication. Can be improved.

  However, since authentication is possible even if there is a distance from the image forming apparatus, there is a possibility that the user may unintentionally log in at an unintended timing. Further, when a user at a position away from the image forming apparatus is authenticated, the user may miss a notification indicating a successful login, or may not know that the user has been authenticated. Therefore, Patent Document 1 discloses a processing device that displays a screen associated with an image of a person existing in a predetermined area close to the processing device.

  In addition, even if a print job is instructed at a terminal such as a personal computer, the image forming apparatus does not immediately execute printing, temporarily stores data in the image forming apparatus, and the user authenticates by the image forming apparatus. There is a deferred print function to execute printing when it is done. Retained printing can suppress neglected printing or prevent information leakage from paper documents. With regard to the reservation printing, there is a demand for the user to receive the print without waiting for the print processing time in front of the image forming apparatus.

FIG. 4 is a block diagram illustrating a configuration of the image forming apparatus 10. The image forming apparatus 10 includes a control unit 100 that controls the operation of the image forming apparatus 10, an operation unit 200, an authentication unit 300, a scanner unit 400, and a printer unit 500.
The control unit 100 can communicate with the operation unit 200, the authentication unit 300, the scanner unit 400, and the printer unit 500.

  Based on a control program or the like stored in the ROM 112, the CPU 110 comprehensively controls access to various connected devices, and also comprehensively controls various processes executed by the control unit 100. CPU 110 communicates with operation unit 200 and authentication unit 300 via input / output I / F 114. Further, the CPU 110 communicates with the scanner unit 400 and the printer unit 500 via the device I / F 118.

  Further, the CPU 110 shifts the power mode of the image forming apparatus 10 from the standby mode to the sleep mode via the power control unit 113 when the image forming apparatus 10 is not used for a predetermined time, such as when the operation unit 200 is not operated for a certain period of time. Let The Standby mode is a standby state in which a reading operation by the scanner unit 400 and a printing operation by the printer unit 500 can be executed according to an instruction. The sleep mode is a power saving state that consumes less power than the standby mode. In the sleep mode, power is supplied only to the processing unit necessary for returning from the power saving state, and the display unit 202 is in a state where the backlight is turned off and nothing is displayed. For example, in the sleep mode of this embodiment, power is supplied only to the LAN controller 115, the power control unit 113, the CPU 201 of the operation unit 200, the CPU 301 of the authentication unit 300, and the sensor 11.

  The RAM 111 is a system work memory for the CPU 110 to operate. The RAM 111 is also a memory for temporarily storing image data. The ROM 112 stores a boot program for the device. The LAN controller 115 is connected to a network such as a LAN (Local Area Network) and communicates with an external device such as a PC (Personal Computer). The HDD 117 is a hard disk drive and stores system software, image data, and the like. The image processing unit 119 reads out image data stored in the RAM 111 and performs image processing such as enlargement / reduction processing and color adjustment.

  The power supply control unit 113 controls the power supply of the image forming apparatus 10 and controls the power supply by an instruction from the CPU 110 or a user operation of a power switch or a power saving button. The power control unit 113 can detect a power-off operation by a power switch, and notifies the CPU 110 of the detected result as a power-off request. When the CPU 110 receives the power-off request, the CPU 110 shifts the image forming apparatus 10 to a state where the power can be turned off, and instructs the power control unit 113 to stop the power.

  The operation unit 200 is for the user to control the image forming apparatus 10 and inputs / outputs information between the image forming apparatus 10 and the user. The operation unit 200 includes a CPU 201, a display unit 202, and an input unit 203. The CPU 201 performs overall control of the entire operation unit 200.

The input unit 203 includes a touch panel, hardware keys, and the like, and receives an operation from the user. Further, the operation unit 200 may include an interface for exchanging data with a mobile terminal held by a user such as an NFC reader / writer or a Bluetooth (registered trademark) module.

The authentication unit 300 performs person detection and person face authentication. The authentication unit 300 includes a CPU 301, a sensor 11, and a camera 14. The CPU 301 performs overall control of the entire authentication unit 300 and performs user authentication based on information acquired by the sensor 11 and the camera 14.
The scanner unit 400 is an image input device that optically reads an image from a document and generates image data. The printer unit 500 is an image output device that forms an image on a recording medium such as paper.

  Next, processing executed by the CPU 301 of the authentication unit 300 will be described with reference to FIG. FIG. 5 is a diagram for describing processing executed by the authentication unit 300. The authentication unit 300 includes a sensor reception unit 320, a person detection unit 321, a distance detection unit 322, a camera reception unit 323, a face detection unit 324, and a face authentication unit 325 as software configurations.

The sensor receiving unit 320 receives data as a detection result from the sensor 11 and transmits the data to the human detection unit 321 and the distance detection unit 322.
Based on the data received from the sensor receiving unit 320, the person detecting unit 321 determines whether or not a person is present in the detection range A1, and transmits the determination result to the power supply control unit 113. The power supply control unit 113 that has received the determination result that the person exists in the detection range A1 from the human detection unit 321 instructs the power supply control unit 113 to supply power to the camera 14.

  The distance detection unit 322 detects the distance from the image forming apparatus 10 to the person based on the data of the sensor reception unit 320, and transmits distance information as a detection result to the face authentication unit 325. As an example of distance detection, a distance detection method using an infrared array sensor will be described with reference to FIG. FIG. 6 is a diagram illustrating a method for measuring the distance from the image forming apparatus 10 to a person.

  In the infrared array sensor, which is the sensor 11, infrared light receiving elements that receive infrared light are arranged in a matrix. The infrared array sensor specifies the shape (detection region) of the heat source as a temperature distribution by using a temperature value based on the amount of infrared light (light reception result) received by each infrared light receiving element. FIG. 6 illustrates an example of an infrared array sensor in which infrared light receiving elements are arranged in a total of 64, 8 rows 1 to 8 and 8 columns a to h. In the following description, when the position of each infrared light receiving element of the sensor 11 is designated, the elements 1a to 8h are indicated.

  FIG. 6A shows the position of a person. The person 601 is at a distance D1 from the image forming apparatus 10. The person 602 is at a distance D2 from the image forming apparatus 10. The distance D2 is a distance shorter than the distance D1. FIG. 6B is a diagram illustrating a detection result of the person 601 located at the distance D1 from the image forming apparatus 10. FIG. 6C is a diagram illustrating a detection result of the person 602 located at the distance D2 from the image forming apparatus 10. The detection results of the infrared array sensor shown in FIGS. 6B and 6C indicate that the darker the color, the higher the temperature.

  In FIG. 6B, the element having the largest row number among the light receiving elements having the highest temperature is the element 5d, and the row number is 5. In FIG. 6C, among the light receiving elements having the highest temperature, the elements having the largest row number are the element 8d and the element 8e, and the row number is 8. As described above, there is a dependency relationship between the row number of the light receiving element having the highest temperature and the distance from the person to the image forming apparatus 10, and the larger the line number, the closer the person is to the image forming apparatus 10. Yes. Therefore, the distance from the image forming apparatus 10 to the person can be detected based on the correspondence between the line number and the distance.

  The method described in FIG. 6 is an example, and the distance can be detected by other methods. For example, distance detection may be performed using a sensor capable of detecting a distance to an object such as an ultrasonic sensor. Further, the distance may be detected based on the size of a specific part of the body detected from the camera image captured by the camera 14 without using the sensor 11. When the camera 14 is used for distance detection, the camera 14 may be configured to include two types of cameras: a wide-angle camera for detecting a person and a camera for photographing a person's face.

The camera reception unit 323 receives an image captured by the camera 14 and transmits it to the face detection unit 324.
The face detection unit 324 determines whether or not a human face exists in the image received from the camera reception unit 323. If the face detection unit 324 determines that a human face exists, the face detection unit 324 transmits an image of a human face part (hereinafter referred to as a face image) included in the image to the face authentication unit 325.

  The face authentication unit 325 calculates feature amount data from the face image received from the face detection unit 324. Then, the face authentication unit 325 collates the dictionary feature amount data, which is feature amount data registered in advance, with the feature amount data acquired from the face image, and the person of the face image receives permission to use the image forming apparatus 10. Authenticate whether or not The face authentication unit 325 transmits the authentication result and the distance information received from the distance detection unit 322 to the CPU 301.

  The CPU 301 that has received the authentication result and the distance information transmits the authentication result and the distance information to the CPU 110 of the control unit 100. When the person imaged by the camera 14 is permitted to use the image forming apparatus 10, the CPU 110 checks whether or not the person's detained print job stays. If there is a reservation print job, the CPU 110 controls the printer unit 500 in accordance with the attached distance information and executes a print process. In addition, the CPU 110 issues a display instruction for displaying a screen corresponding to the person on the display unit 202 according to the distance information to the operation unit 200. For example, the CPU 110 issues a display instruction when the person arrives within the second designated range R2. The CPU 201 in the operation unit 200 that receives the display instruction from the CPU 110 displays a screen corresponding to the authenticated person setting on the display unit 202 in accordance with the display instruction. On the other hand, when the person imaged by the camera 14 has not received permission to use the image forming apparatus 10, the CPU 110 displays a screen for performing authentication by a method other than face authentication, such as ID authentication or IC card authentication. An instruction to be displayed on the unit 202 is given.

FIG. 7 is a diagram illustrating an example of a screen displayed on the display unit 202. FIG. 7A is a diagram illustrating an example of an ID authentication screen. FIG. 7B is a diagram illustrating an example of the screen after authentication.
In face authentication processing by the camera 14, if face authentication is not successful due to lack of a face image for authentication or the like, authentication by a method other than face authentication needs to be performed. When the face authentication is not successful, for example, the CPU 110 causes the display unit 202 to display an ID authentication screen for inputting a user name (or ID) and a password, and performs ID authentication. When authentication by face authentication or ID authentication is successful, the display unit 202 displays a screen after authentication corresponding to the authenticated person. On the screen after authentication, information indicating the authenticated person such as a user name and ID is displayed together with an operation screen such as “copy” and “scan”. By displaying information indicating the authenticated person such as the user name and ID, it is possible to confirm who is authorized by the user, that is, whether the user can log in with his / her information.

  8 and 9 are flowcharts showing the flow of the face authentication process. In this process, a series of processes for performing human detection, face authentication, automatic execution of reserved printing and screen display will be described. These measures are executed by the CPU 110 of the control unit 100, the CPU 301 of the authentication unit 300, and the CPU 201 of the operation unit 200. Specifically, the procedures from S801 to S805 are stored in the ROM 112 and executed by the CPU 110. The procedures from S901 to S904 are stored in a storage area (not shown) of the CPU 201 and executed by the CPU 201. The procedures from S701 to S709 are stored in a storage area (not shown) of the CPU 301 and executed by the CPU 301.

The processing of FIGS. 8 and 9 shows a case where the power mode of the image forming apparatus 10 is started in the sleep mode.
First, processing executed by the authentication unit 300 will be described.
In step S <b> 701, the CPU 301 performs a person detection process using the sensor 11. The human detection process is always performed in the sleep mode.
In step S702, the CPU 301 determines whether a person has been detected. If it is determined that a person has been detected, the process proceeds to S703. On the other hand, if it is determined that no person is detected, the process returns to S701 and the person detection process is continued.

  In step S <b> 703, the CPU 301 acquires the distance from the image forming apparatus 10 to the person using the distance detection unit 322, and determines whether the distance to the person is within the first specified range. The first designated range is a range in which a human face is photographed for face authentication processing by the camera 14, and is set in the image forming apparatus 10 in advance by a user or an administrator. In the present embodiment, for example, a range within 3.0 m from the image forming apparatus 10 is set as the first designated range. If it is determined that the distance from the image forming apparatus 10 to the person is within the range of the first designated range, the process proceeds to S304. On the other hand, when it is determined that the distance from the image forming apparatus 10 to the person is outside the range of the first designated range, S703 is repeated.

  In step S <b> 704, the CPU 301 is activated by turning on the power of the camera 14, and performs face authentication processing using the camera 14. If the camera 14 is already turned on, only face authentication processing is performed. The face authentication process is performed by the face detection unit 324 and the face authentication unit 325 based on the image captured by the camera 14.

In step S <b> 705, the CPU 301 determines whether face authentication by the camera has been completed. If it is determined that the face authentication process has been completed, the process proceeds to S706. On the other hand, if it is determined that the face authentication process has not been completed, S705 is repeated. In addition, when the process of S705 passes for a fixed time, you may make it complete | finish this process by timeout.
In step S <b> 706, the CPU 301 transmits the authenticated user ID to the control unit 100 as the authentication result of the face authentication process in step S <b> 704.
In step S <b> 707, the CPU 301 transmits distance information to the person acquired in step S <b> 703 to the operation unit 200. Therefore, the distance information transmitted in S707 is the distance information acquired when the person enters the first designated range.

In step S <b> 708, the CPU 301 obtains the distance from the image forming apparatus 10 to the person again by the distance detection unit 322, and determines whether the distance to the person is within the second specified range. The second designated range is a distance at which the user can confirm the display content of the display unit 202, and is set in the image forming apparatus 10 in advance by the user or an administrator. In the present embodiment, for example, a range within 0.5 m from the image forming apparatus 10 is set as the second designated range. If it is determined that the distance to the person is within the range of the second designated range, the process proceeds to S709. On the other hand, if it is determined that the distance to the person is outside the range of the second designated range, S708 is repeated.
In step S <b> 709, the CPU 301 transmits the distance information acquired in step S <b> 708 to the operation unit 200, and ends the flowchart relating to the CPU 301. Therefore, the distance information transmitted in S709 is the distance information acquired when the person enters the second designated range.

Next, processing executed by the control unit 100 will be described.
In step S <b> 801, the CPU 110 receives an authentication result by face authentication from the authentication unit 300. The received authentication result is the user ID of the authenticated user transmitted by the authentication unit 300 in S706.
In step S802, the CPU 110 permits login of the user ID received in step S801.

In step S803, the CPU 110 acquires job information of the logged-in user. The job information is information indicating whether there is a deferred job associated with the logged-in user.
In step S <b> 804, the CPU 110 determines whether there is a deferred job corresponding to the logged-in user based on the acquired job information. If it is determined that there is a deferred job, the process proceeds to S805. On the other hand, if it is determined that there is no deferred job, this flowchart relating to the CPU 110 is ended.
In step S <b> 805, the CPU 110 prints the reservation job and ends the flowchart relating to the CPU 110.

Next, processing executed by the operation unit 200 will be described.
In step S <b> 901, the CPU 201 receives distance information in the first designated range from the authentication unit 300.
In step S <b> 902, the CPU 201 displays a screen displayed before authentication, such as the ID authentication screen illustrated in FIG. 7A, on the display unit 202. In this embodiment, after the authentication is successful, the distance information in the first designated range is transmitted from the authentication unit 300 to the operation unit 200, and the screen before authentication is displayed on the display unit 202. It is not limited to. For example, when it is determined in S303 that the distance to the person is equal to or less than the first designated range, the distance information in the first designated range is transmitted from the authentication unit 300 to the operation unit 200, and the pre-authentication is displayed on the display unit 202. The screen may be displayed.

In step S <b> 903, the CPU 201 determines whether distance information in the second designated range has been received from the authentication unit 300. If it is determined that the distance information in the second designated range has been received, the process proceeds to S904. On the other hand, if it is determined that the distance information in the second designated range cannot be received, the process of S903 is repeated. If no distance information is received in the second designated range, the process may be terminated due to a timeout after a predetermined time.
In step S904, the CPU 201 displays a screen (custom display screen for each user) corresponding to the authenticated user. For example, the CPU 201 displays a screen including the user name shown in FIG. 7B as the screen corresponding to the authenticated user.

  As described above, the display unit 202 displays the pre-authentication screen in response to the user being authenticated in the first specified range, and the authenticated screen in response to the user entering the second specified range. Is displayed. Since the screen after authentication can be displayed at a distance at which the user can check the display unit 202, the user can check that he has logged in. Further, since the control unit 100 executes a job in response to the user entering the first designated range, the control unit 100 executes the job while the user approaches the image forming apparatus 10 until the user completes the job. The waiting time can be shortened.

The operation of the image forming apparatus 10 when the person 30 approaches the image forming apparatus 10 will be described with reference to FIG. FIG. 10 is a diagram for explaining the operation when a person approaches the image forming apparatus 10. It is assumed that the person 30 has previously submitted a print job from the personal computer to the image forming apparatus 10.
First, when the person 30 enters the detection range A1 of the sensor 11, the image forming apparatus 10 detects the person 30 (S701). When the person 30 enters the first designated range R1, the image forming apparatus 10 activates the camera 14 and starts the face authentication process with the camera 14 (S704). When the face authentication is completed, the image forming apparatus 10 executes a user login process for the authenticated person 30 (S802). As a result, the user authentication waiting time can be reduced to zero, and a highly convenient face authentication login function can be provided to the user. Further, the image forming apparatus 10 executes a job for retaining the person 30 (S805). When the user enters the first designated range R1, the print is automatically executed without any operation by the user, thereby suppressing the time for waiting for the job to be executed in front of the image forming apparatus 10 and having high convenience. It is possible to realize a retention print function. When the person 30 further approaches the image forming apparatus 10 and enters the second designated range R2, the display screen of the display unit 202 changes from the pre-authentication screen to the authenticated post-authentication screen unique to the user. Accordingly, the person 30 can confirm that the authentication process has been performed by confirming the display screen.

  As described above, according to the present embodiment, the person approaching the image forming apparatus 10 is authenticated, and if the authentication is successful, the holding job is automatically executed, and the person further approaches the image forming apparatus 10. The user screen can be displayed at the timing. Therefore, while providing highly convenient functions such as automatic execution of a deferred job by face authentication processing, it is possible to reduce the user's anxiety by showing that the user has been authenticated at the timing when the user can visually recognize the image. A forming apparatus can be provided.
